no link at all, it just happened to be noticed then (only that I boosted the levels to reach near fullscale), and I used to have other default hdspmixer settings. > Anyway, this is still an 'easy' test, it doesn't stretch the > hardware to any limits at all. Sure, that is the reason why I cut the silence away - there you can hear clear differences. > > The difference between the Behringer and the Micstasy is not > about 'audio quality' in the sense of frequency response, > distortion, etc. It would take really bad engineering to get > those so bad that it would matter. > > It is all about technical qualities that *do* matter if things > get a bit more difficult: hum levels, noise levels, the ability > to change the mic gain while recording without any risk and by > a defined amount, resistance to RF and mains interference, being > able to supply stable phantom power on all inputs, etc. etc. I totally agree, my B.s drove me almost crazy several times. For concerts (where I need 3 of them) I always have a spare one reachable. > Try recording a contemporary music concert on location, with > percussion ranging from barely audible scratches to a bing bang, > and voices switching between whispering and screaming in a matter > of seconds. This sort of thing even takes a Micstasy or an Aphex > 1778A to its limits. Your B. will fail miserably. I did that as well a few weeks ago, and by B. failed :-) Right now I don't have additional 4kEUR just for reliability, that's why I still use my B.s (except when I can borrow a Micstasy), but I cannot wait the day when I say good bye to them...
